Resources disappear from the map
from
Stardock Forums
If you discover a resource to put a starbase on, it will only stay visible as long as a planet or ship is near it, if not it disappears.
I think that this should be changed; once you discovered it it should stay visible. After all if you, James T. Kirk, would find one you would make sure that the exact coordinates would be entered into your database for future mining.
(Maybe James T. Kirk wouldn't because he would be to busy fiddling about with some alien knock-out. But Janeway or Picard would certainly be responsible enough :))
